[0002] Polyethylene pipe (PE pipe) is a pipe made of polyethylene material. As a polymer material, polyethylene has excellent physical and chemical properties, which gives PE pipes many advantages and is widely used in the fields of water transportation, gas, sewage treatment, power and communication cable protection. In field concrete roads, PE pipes are usually laid under the concrete road to distribute water from the main pipeline to various irrigation areas.
[0003] In rural drinking water projects, PE pipes are usually buried along existing concrete roads to facilitate construction and subsequent water supply. This trenching and pipe laying method not only saves ground space, but also avoids the complex issues of land acquisition and coordination. However, traditional PE pipes face some challenges when buried under concrete pavement. Due to the lack of external support and protection structure, the weight and pressure of the concrete pavement may cause corrosion and mechanical damage to the PE pipes, which will shorten the service life of the PE pipes and pose a threat to water supply safety.
[0004] Therefore, we proposed a PE pipe structure suitable for field concrete roads to solve these problems and extend the service life of PE pipes. Utility Model Content

[0025] See also Figure 3-4 The first support and protection assembly 3 has the same structure as the second support and protection assembly 4. The first support and protection assembly 3 includes a first support member 12, and the bottom of the first support member 12 is connected to the second support member 13. The combined use of the first support member 12 and the second support member 13 enhances the stability of the entire support and protection mechanism 2. When the bottom of the first support member 12 is connected to the second support member 13, the first support member 12 and the second support member 13 can form a strong support structure that can effectively support and fix the PE pipe to prevent it from displacement or shaking during use. The first support member 12 includes an upper pressure cover plate 14, and snap-in grooves 15 are respectively provided at the two side edges of the upper pressure cover plate 14. The snap-in connection between the first support member 12 and the second support member 13 is provided through the snap-in connection grooves 15 respectively provided at the two side edges of the upper pressure cover plate 14.
[0026] See also Figure 5 The second support member 13 includes a lower pressure cover plate 16, and snap-in plates 17 are respectively installed at the edges of both sides of the lower pressure cover plate 16. The snap-in plates 17 match the structure of the snap-in groove 15, and the snap-in plate 17 and the snap-in groove 15 are snap-fitted. Two groups of positioning holes 18 are opened at one end of the lower pressure cover plate 16 and the upper pressure cover plate 14, and two groups of positioning pins 19 are connected to the end of the lower pressure cover plate 16 and the upper pressure cover plate 14 away from the positioning holes 18. The positioning pins 19 match the structure of the positioning holes 18, and the positioning pins 19 and the positioning holes 18 are plug-fitted. Through the snap-fitting structural design between the snap-in plates 17 and the snap-fitting grooves 15, the upper pressure cover plate 14 and the lower pressure cover plate 16 sleeved on the outside of the water supply pipeline 1 can be snap-fitted and fixed, and the stability of the connection between the upper pressure cover plate 14 and the lower pressure cover plate 16 can be improved.

[0028] Working principle: The water pipeline 1 designed in this scheme consists of two parts: an inner water pipe 5 and an outer protective pipe 6. The metal support mesh 9 installed between the inner water pipe 5 and the outer protective pipe 6 can not only play a role in connecting and fixing the inner water pipe 5 and the outer protective pipe 6, but also enhance the rigidity and pressure resistance of the overall structure of the water pipeline 1. In combination with the buffer cavities 10 opened inside the inner water pipe 5 around each other, it can not only absorb and disperse the pressure from the outside, but also optimize the impact resistance of the overall structure of the water pipeline 1, so as to ensure the smooth flow of water in the water pipeline 1. The support and protection mechanism 2 installed outside the water pipeline 1 can ensure the smooth flow of water in the water pipeline 1. The protective mechanism 2 can clamp and fix the upper pressure cover plate 14 and the lower pressure cover plate 16 sleeved on the outside of the water pipe 1 through the structural design of the clamping fit between the clamping plate 17 and the clamping groove 15, which can improve the stability of the connection between the upper pressure cover plate 14 and the lower pressure cover plate 16. With the structural design of the plug-in fit between the limiting groove 21 and the limiting plate 7, the upper pressure cover plate 14 and the lower pressure cover plate 16 sleeved on the outside can also play a role of clamping and limiting the surrounding of the water pipe 1, which can improve the connection stability between the water pipe 1 and the supporting protective mechanism 2, and can also prevent the water pipe 1 from shaking inside the supporting protective mechanism 2 during the use of water delivery;
[0029] From the above, it can be seen that the PE pipe structure of the field concrete road designed in this scheme greatly improves the stability and durability of the water pipeline 1 through the multi-layer protection structural design. This multi-layer protection structure can effectively prevent the corrosive substances and mechanical pressure under the concrete road surface from damaging the PE pipe, thereby extending the service life of the pipeline and reducing the frequency of maintenance and replacement.
